Pinault’s donation is the first major one announced. Through Kering, an international luxury group, his family owns and controls a number of businesses including Gucci, Alexander McQueen, Stella McCartney, Saint Laurent and Balenciaga.

The elder Pinault, who is 82, is worth an estimated $37.3 billion, according to Bloomberg’s “Billionaires Index“.

He continued, “It is with pride I tell you tonight we will rebuild this cathedral . . . we will rebuild Notre Dame because it is what the French expect of us, it is what our history deserves, it is, in the deepest sense, our destiny.”
